The PPE 115900500 Silicone Coupling is designed as a direct replacement for your 2004.5-2016 GM 6.6L Duramax. Competitive and high performance applications can put huge stress on the factory hoses in your truck. PPE's hoses were designed to far exceed the quality of the OE components and will handle the rigors of increased pressure in racing and competition.
Each PPE Performance Silicone Hose is strengthened with 5 plies of polyester reinforced fibers making them very tough. The Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures that they can withstand constant boost pressures from -76 degrees all the way to +437 degrees Fahrenheit. In short, PPE Performance Silicone Hoses will not blow out like a stock hose will.
PPEs Silicone Hoses are resistant to fuel, oil and chemicals while also being UV and Ozone resistant. These hoses can handle the extreme exposure that heavy usages puts upon them. With multiple sizes and configurations, there is a PPE Performance Silicone Hose for every design application.
